Seal the shaft with a packed stuffing box

WARNING:
Packed stuffing boxes are not allowed in an ATEX-classified environment.

Pumps are shipped without the packing, lantern ring, or split gland installed. These parts are included with
the box of fittings shipped with each pump and must be installed before startup.
1. Carefully clean the stuffing-box bore.
2. Twist the packing enough to get it around the shaft.

3. Insert the packing and stagger the joints in each ring by 90°.

Install the stuffing-box parts in this order:
a) Two packing rings
b) One lantern ring (two-piece)
c) Three packing rings

NOTICE:
Make sure that the lantern ring is located at the flushing connection to ensure that flush is obtained.
Failure to do so may result in decreased performance.

4. Install the gland halves and evenly hand-tighten the nuts.

Seal the shaft with a cartridge mechanical seal

WARNING:
The mechanical seal used in an Ex-classified environment must be properly certified. Prior to startup,
make sure that all areas that could leak pumped fluid to the work environment are closed.

NOTICE:
The mechanical seal must have an appropriate seal-flush system. Otherwise, excess heat generation and
seal failure can occur.

1. Slide the cartridge seal onto the shaft or sleeve until it contacts the inboard labyrinth oil seal.
2. Assemble the seal chamber.
3. Slide the cartridge seal into the seal chamber and secure using the four studs and nuts.
4. Continue with the pump reassembly.
